I will add my concern for this issue. I have a significant number of resources that I prefer to keep separate from my personal photos and other media, and to not be able to access them from directly within RW7, as advertised and expected, makes my user experience more cumbersome. Not an impossible situation, but if it’s being touted as a feature, then it is something that needs to work.
